Overview
Brief Summary
This phase I trial studies the side effects and best dose of olaparib and onalespib when given together in treating patients with solid tumors that have spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable) or ovarian, fallopian tube, primary peritoneal, or triple-negative breast cancer that has come back (recurrent). Olaparib and onalespib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Detailed Description
PRIMARY OBJECTIVE: I. To establish the maximum tolerated dose (MTDs) of olaparib and onalespib (AT13387) administered in combination in patients with advanced solid tumors. SECONDARY OBJECTIVES: I. To identify the dose-limiting toxicity (DLT) and other toxicities associated with olaparib and AT13387 administered in combination as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. II. To determine the recommended phase 2 doses (RP2D) of the combination of olaparib and AT13387. III. To determine the plasma pharmacokinetics of olaparib and AT13387. IV. To document anti-tumor activity of the combination of olaparib and AT13387 as assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and progression free survival (PFS). Although the clinical benefit of \[this/these\] drug(s) has not yet been established, the intent of offering this treatment is to provide a possible therapeutic benefit, and thus the patient will be carefully monitored for tumor response and symptom relief in addition to safety and tolerability. OUTLINE: This is a dose-escalation study. Patients receive olaparib orally (PO) twice daily (BID) on days 1-7 (cycle 0). Beginning in cycle 1, patients receive olaparib PO BID on days 1-28 and onalespib intravenously (IV) over 1 hour on days 1, 2, 8, 9, 15, and 16. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days and every 3 months for up to 2 years.

Eligibility Criteria
Inclusion Criteria
- •For the dose escalation cohort, patients must have histologically or cytologically confirmed malignancy that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective
- •For the dose escalation cohort, patients may have received any number of prior therapies
- •For the dose expansion cohort, participants must have histologically or cytologically confirmed diagnosis of either:
- •Ovarian, fallopian tube, or primary peritoneal cancer of high grade serous histology which has recurred despite standard therapy; up to 3 prior lines in the platinum resistant setting (i.e. up to 3 lines after patients have become platinum resistant); patients may have received unlimited lines while platinum sensitive
- •Triple-negative breast cancer (TNBC) which has recurred despite standard therapy; recurrent TNBC needs to have metastatic disease and patients with an in breast recurrence are not eligible; up to 4 prior lines in the recurrent setting for patients with triple-negative breast cancer are allowed
- •For the dose expansion cohort, patients with ovarian, fallopian tube or primary peritoneal cancer must have platinum resistant disease defined as progression within 6 months after last platinum regimen; platinum refractory disease is allowed
- •For the dose expansion cohort, patients with triple-negative breast cancer may not be BRCA1/2 germline mutation carriers
- •Because no dosing or adverse event data are currently available on the use of olaparib in combination with AT13387 in patients \< 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials.
- •There must be availability of a formalin-fixed, paraffin-embedded tumor specimen
- •Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 (Karnofsky \> 60%)
Exclusion Criteria
- •Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
- •All acute, clinically significant treatment-related toxicity from prior therapy, except for alopecia, must have resolved to grade =\< 1
- •Patients who are receiving any other investigational agents
- •Patients with known active or history of brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to olaparib and AT13387 used in study
- •Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- •Pregnant women are excluded from this study because olaparib and AT13387 are agents with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with AT13387 or olaparib, breastfeeding should be discontinued if the mother is treated with olaparib or AT13387
- •Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with olaparib or AT13387; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
- •Known history of QT/corrected QT (QTc) prolongation or torsades de pointes (TdP); patients who are currently receiving treatment with medication with a known risk to prolong the QT interval or inducing torsades de pointes and the treatment cannot either be discontinued or switched to a different medication prior to starting study drugs
- •Participants receiving any medications or substances that are strong inhibitors or inducers of CYP3A4 or moderate inhibitors of CYP3A4 are ineligible; the study team should check a frequently-updated medical reference for a list of drugs to avoid or minimize use of; as part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product

Outcomes
Primary Outcomes
Maximum Tolerated Dose (MTD) of Olaparib Administered in Combination With Onalespib
Time Frame: Up to 35 days for each dose level cohort
MTD was determined by testing increasing doses of the combination of olaparib PO and onalespib IV within dose escalation cohorts consisting of 3 to 6 evaluable participants. MTD reflects the highest dose combination that did not cause a Dose-Limiting Toxicity (DLT) in \> 33% of participants. DLTs were defined based on the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Enrollment to this study was suspended prior to completion of the dose escalation due to discontinuation of further development of onalespib. A true single MTD therefore could not be determined. The two dose levels included in this outcome measure represent the highest well-tolerated dose combinations (Dose Level 2 \[DL2\]: Olaparib 300 mg PO BID and Onalespib 40 mg/m\^2 IV; and Dose Level 2a \[DL2a\]: Olaparib 200 mg PO BID and Onalespib 80 mg/m\^2 IV).
